Simplify completely quantity x squared plus 4 x minus 45 all over x squared plus 10 x plus 9 and find the restrictions on the va
riable. A) quantity x minus 5 over quantity x plus 1, x ≠ −1, x ≠ −9
B) quantity x minus 5 over quantity x plus 1, x ≠ −1, x ≠ 5
C) quantity x plus 5 over quantity x plus 1, x ≠ −1, x ≠ −9
D) quantity x plus 5 over x plus 1, x ≠ −1, x ≠ 5
It is D parabola because in a double right circular cone the vertex is in the middle of two opposite cones and cutting through the vertex is making parabola.
